In bowl, place golden raisins, vinegar, 2 Tbsp water, and 1/4 tsp salt. Stir together contents and let rest for at least 30 minutes.
In medium saucepan, place freekeh, 3 1/2 cups water, and a couple pinches of salt. Bring to a boil; reduce heat to low and simmer, covered, for 30 minutes, or until freekeh is tender. Drain away any liquid that remains in the pot. Set freekeh aside in pot and let rest, covered, for 10 minutes, then fluff with a fork.
In large bowl, place freekeh and toss with navy beans, chickpeas, kale, tomatoes, parsley, pistachios, and pickled raisins.
In small bowl, whisk together lemon juice, olive oil, garlic, and remaining 1/4 tsp salt. Toss lemon dressing with freekeh mixture.
